Sapphire was one of those china doll that looks creepy and beautiful at the same time. Pale face, cracks on the side of his face, soft white hair, beautiful blue eyes that look like they're alive. sapphire was beautiful but oddly eerie.
But there was another reason why Sapphire was different from other dolls.
Sapphire was alive.
And being alive comes with a consequences of danger, when you're in a world where people are afraid of living dolls like sapphire.
